A lens barrel and an image pickup apparatus using the same are disclosed. The lens barrel includes a guide bar which guides a first lens unit in a direction of an optical axis, a shift unit which shifts a second lens in a direction perpendicular to the optical axis, and a recess portion which is formed in a member which constitutes part of the shift unit, in such a manner as to recede in the direction perpendicular to the optical axis, the guide bar being passed through the recess portion. The guide bar is disposed at a position as close to the optical axis as possible so that the size of the lens barrel is reduced.
